Freelancer Overview

I am a data analyst with hands-on experience in data annotation and AI data quality, specializing in ensuring the accuracy and reliability of training datasets. In my recent role as an AI Data Quality Analyst, I evaluated over 100 unstructured AI-generated responses monthly, identifying inconsistencies and documenting quality risks to support better model training. My technical toolkit includes advanced Excel, SQL, and Power BI for data analysis and visualization, along with foundational skills in Python and ongoing learning in Tableau. I have also contributed to projects involving HR analytics, sales and market analysis, and process optimization, where I applied statistical methods and built interactive dashboards to uncover actionable insights. My background in scientific research and data-driven process improvement further strengthens my attention to detail and commitment to data integrity in labeling and annotation tasks.
